STEAM WATER HEATER.

Application led November 13, 1922. Serial No. 600,504.

To aZZ whom t may conce/m Be it known that I, CUTHBERT LAVINGTON DIXON,a subject of the King of Great Britain, and residing at the city ofMontreal, in the Province of Quebec, in the Dominion of Canada, haveinvented anew and useful Steam Water Heater, of which the following isthe specification.

The invention relates to heating devices as described in the presentspecification and shown in the accompanying drawings that form part ofthe same.

The invention consists essentially of the novel features pointed outbroadly and speciiically in the claims for novelty following adescription containing an explanation in detail of an acceptable form ofthe invention.

The objects ofthe invention are to econ omize in the consumption of fuelby directing the flow of water so that there is an effectivedistribution of the heat around and about the stream; to maintain aquantity of otherwise in which it may be used; to furnish satisfactoryhot water heating systems in houses, commercial and public buildings andplants; to facilitate assembling of the parts in such devices andrepairing and replacing of parts; to reduce the oost of maintenance inheating plants; and generally to provide in such devices a heatingsurface great in respect to the size of the plant and at the same timecheap to provide, efficient in use and of a durable nature.

In the drawings, Figure 1 is a longitudinal sectional view of a casingshowing the tubes and header in section.

Figure 2 is al cross sectional View on the line 2 2 in Figure 1.

Figure 3 is a cross sectional view on the line in Figure l.

Figure 4 is a cross sectional view on the line 4-4 in Figure 1.

Like numerals of reference indicate corresponding partsv in the variousfigures.

Referring to the drawings the header indicated by the numeral 1 isformed with an outer end wall 2, a longitudinal outer wall 3, an innerend wall4 and an intermediate wall 5 and through the outer end wall 2the water inlet 6 at the lower end and the water outlet 7 at the upperend lead to the inlet chamber 8 and from the outlet chamber 9.

The intermediate outer chambers 10 and titions 18 and 19 and from theoutlet chamber 9 by the 'partition 20, the partitions 18, 19 and 20extending' from the intermediate wall 5 to the inner wall 4.

Threaded orifices 21 are made through vthe inner wall 4 for the outertubes and threaded orifices 22 are made through the intermediate wall 5for the inner tubes.

The inner tubes in rows 23, 24, 25, 26, 27, 28 and 29 are open at bothends and screwed into the tube orifices 22 and are therefore incommunication with the chambers 8, 9, 10V

and 11, there beingy two rows of tubesto each chamber except the outletchamber 9, which has only the one row 29 emptying thereinto.

rlhe outer tubes in rows 30, 31,32, 33, 34, i

35 and 36 are closed at one end 37 either capped or welded and at theiropen ends they are screwed into the tube. orifices 21 and contain themajor portion of the said inner tubes, the latter being of much smallerdiameter and' terminating at one end short of the length of said outertubes and at their other end projecting from the mouths of the outertubes to the intermediate wall 5.

The shell 38 encloses both the inner and outer tubes and is rigidlysecured to the header 1 and also contains the storage tank 39 which isof segmental shape in cross section and is rigidly secured by theflanges 40 and 41 and spaced from the shell and located immediatelyabove the tubes, having the opening 42 leading to and from the outletchamber 9, in order that the water may be free to flow in and out.

The steam inlet 43 leads intov the shell 38 and is connected inoperation to a suitable steam plant and the steam outlet- 44 leads fromthe shell. The steam inlet and outlet are shown as through the upperside of the shell, but they may be placed, where the most efliciency isassured.

The condensation drain 45 is through the bottom of the shell 38.

ln the operation of this heating device the Water inlet is connected toa suitable Water supply and the outlet to the heating system or suchother arrangements according to the conditions of use. rlhe Waterentering at the inlet flows into chamber 8 and through the inner tubes23 and 24 from said chamber to the ends of the corresponding outer tubes30 and 31 returns along the said outer tubes 30 and 3l.

Emptying from the tubes 8O and 3l into the chamber l5, it flows into thetubes 32 and along said tubes to the closed ends and back by the tubes25 to the chamber l0. F rom the chamber .l0 the Water flows through thetubes 26 to the end ot the tubes 33 and back through the latter to thechamber 16. The Water then flows along the tubes 3a and back throug'hthe tubes 27 into the chamber l1 from Which it flows through the tubes28 and back by the tubes 35 to the chamber 17 and thence along the tubes36 and back through the tubes 29 to the outlet chamber S) Where it flowsto the various parts of the circulating system alter filling the storagetank 39. The steam is distributed throughout the interior of the shell38 flowing over and about the storage tank and around all the outertubes. This may be reversed it desired and have the Water in the shelland the steam in the tubes.

It may be here mentioned that tubes 29 shown in one row are preferablytwice the diameter of the other inner tubes in order to permit the flowof lan increased volume ot Water, though it may be arranged by havingmore tubes.

What I claim is:

l. A steam Water heater, comprising a header having inner and outerWater chambers, the lovver outer chamber forming an inlet compartmentand the upper outer chamber torming an outlet compartment, inner andouter pipes communicating With said outer and inner chambersrespectively to term a passage between said inlet and outlet Ycompartments, a cylinder enclosing said pipes and a longitudinal hotWater chamber above said pipes and spaced from the cylinder Wall at thetop and secured to the end wall thereotl and to said head andcommunieating With the outlet chamber in said head.

2, lnheating devices, a header having inner and outer end Walls, anintermediate Wall and partitions forming inlet, outlet and intermediatechambers, a storage tank communicating With said outlet chamber, a shellenclosing said storage tank and secured to said header and tubesconnected to the. inner and intermediate. Walls and providingcommunication` between the inlet, intermediate and outlet chambers.
